Specification of Letters Patent.

Patented Sept. 11, 1906.

Application filed March 17. 1906. Serial No. 806.486.

To all whom it may concern:

Be it known that 1, AUGUST F. AHLSTRAND, a subject of the King ofSweden, residing at Bridgeport, in the county of Fairfieldand State ofConnecticut, have invented anew and useful Improvement in Machines forTipping Corset-Steels; and I do hereby declare the following, when takenin connection with the accompanying drawings and the letters and figuresof reference marked thereon, to be a full, clear, and exact descriptionof the same, and which said drawings constitute part of thisspecification, and represent, in

Figure 1, a front view of a machine constructed in accordance with myinvention; Fig. 2, a top or plan view of the same; Fig. 3, a side viewof the right-hand side of the machine; Fig. 4, a broken sectional viewon the line a b of Fig. 8 Fig. 5, a broken side view of the clamping-bardetached; Fig. 6, a broken section view illustrating the position of asteel preparatory to first pasting" the end thereof; Fig. 7, a similarsection showing the slide moved forward to primarily paste the steel;Fig. 8, a broken sectional view illustrating the mechanism for feeding apaper strip; Fig. 9, a broken sectional view showing a strip just as itis being out; Fig. 10, a broken sectional view illustrating the meansfor operating the cutters; Fig. 11, a-broken plan view of the same; Fig.12, a view similar to the parts shown in Fig. 8, showing the severed tipat the end of the steel preparatory to being folded thereupon; Fig. 13,a broken sectional view showing a tip folded upon the steel; Fig. 14, abroken sectional view illustrating the final clamping or pressing jaws;Fig. 15, a broken plan view of a steel having tips applied thereto.

The ends of corsetsteels as they come from a cutting-machineare liableto have a rough edge, which, after being placed in a corset, are liableto out through the fabric. It is customary, therefore, to place upon theends of these steels a short strip of cloth or paper, giving the ends asmooth edge, the

material corresponding in width to the width of the steel. Variousdevices have been arranged for placing these tips on the steels; and theobject of this invention is the arrangement of an automatic machine totake I the steels one by one from ahopper, apply the tips of paper orcloth to the ends thereof, and discharge them in a finished condition;and the invention consists in the construction hereinafter described,and particularly recited in the claims.

The machine is built in two parts, so that,

if desired, both ends of a steel may be simultaneously tipped; but onlyone side of amachine need be operated if it is desired to tip only oneend of a steel, and for convenience of illustration I will describe oneside of the machine together. with such mechanism as may be necessary toconnect the two parts.

The steels 2 are placed in a hopper 3 at the front of the machine, thishopper being of suitable form to properly hold the steels one aboveanother. Below the hopper is a slide 4, carrying a hook 5, adapted totake the lowermost steel from the hopper and move it one step to therear. The slide moves back and forth in the frame 6, the slide beingoperated by a lever 7, carrying a stud 8, which rides in a cam-groove 9in a cam-wheel 10, mounted on a shaft 11. Also carried by the slide area series of dogs 12, 13, 14, and 15, while above the slide 4 is aclamping-plate 16, below which and parallel therewith 1s a clamping-bar16, mounted at the upper end of two arms 17 and 18, which are connectedby a brace 19 at the bottom, by which the clamping-bar is raised andlowered by means of a bell-crank lever 20, pivoted at 21 and having itsupper end connected by a link 22 with a cam-arm 23, pivoted to the frameand operated by a cam 24 on the shaft 11. V

In rear of the hopper 3 is a primary pasting-cup 25, having in its sidenear its bottom a slot 26, and this cup is mounted on atransversely-movable slide 27, operated by being connected with theupper end of an elbow cam-lever 28, pivoted at 29 and carrying a stud30, which rides in a cam-groove 31 of a cam 32 on the shaft 33.

When the inward movement of the slide takes place, the first steel hasbeen moved rearward by the hook 5 into line with the primary paste-cup25, where it is clamped by the clamping-bar l6 against the clampingplate16, so that as the cup moves forward it will pass onto the end of thesteel which enters the slot 26 and receives a coating of paste. Whilethe steel is thus engaged and being coated, the slide 4 moves forwardfor the hook 5 to engage with a second steel, while the dog 12 rises infront of the first steel and ready to advance it at the next step. At

. fabric the lower end of the strip is gripped by a movable jaw 39, theupper end 40 of which clamps the end of the paper against a second jaw41, these jaws being arranged to movevertically in a housing 42, formingpart of a slide 42. The jaws 39 and 41 are raised and lowered by acam-slide 41 moved by a short lever 43, mounted upon a stud 44, fixed tothe frame and formed at its outer end with a groove 45, which sets overor rides upon a pin 46, mounted upon a link 47, which is connected withthe cam-slide 41 and pivoted to an arm 48, depending from the slide 42*,the lever 43 being raised and lowered by means of a pin 49, carried byit and riding in a camgroove on a cam 5O on the shaft 33. At the propertime the cam-slide 41 rises, and the end of the strip of paper or fabric35 is grasped below a guide 51, through which it passes, having beencoated, as before described, on one side with paste. The camslide thendescends, drawing the strip with it across the end of the steel in linetherewith, the steel being again held at this point by the clamping-bar16 against the clamping-plate 16. When thus drawn downward, the end ofthe strip is severed by a blade 52, coacting with a stationary blade 53.The blade 52 is secured to a lever 54, which is mounted on a post 54",secured to the bed of the machine. The blade is moved back and forth bya lever 55, actuated through a link 56, pivoted at 57 to the bed of themachine and actuated at its lower end by a cam 58 on the shaft 33.

To prevent undue movement of the j aw 41, I arrange a friction-plate 59adjacent to it and, by means of a spiral spring 60, hold the plate incontact with the jaw. The frictionplate also takes the wear upon the jaw41 and.

prevents that jaw 41 wearing the adjacent part of the machine.

Two jaws 61 and 62 are arranged in line with the steel and are mountedupon the slide 42*, while the slide 27 carries a pin 63, which passesbetween the jaws 61 and 62 and normally holds them open. The firstmovement of the slide 27 moves the pin from between the jaws into aclearance-space 64, arranged between them, allowing the extreme ends 65and 66 to come together, the jaws being normally drawn together by aspiral spring 67, mounted upon a pin 68, passing through the jaw 61 intothe jaw 62. Depending from the slide 27 is a lug 69, which rides in aslot in the slide 42 and by the continued movement of the slide 27 movesthe slide 42*, which is moved in the opposite direction by theengagement of the end of the slide 27 with a shoulder 70 on the slide 42This forward movement of the slides 27 and 42 moves the jaws against thesevered strip of paper and carries it over the end of the steel, foldingit down on the opposite sides thereof, as shown in Fig. 13. The nextmovement of the slide advances the two steels thus acted upon and feedsa third one from the hopper to the primary pasting-cup, the coveredsteel being advanoed by the dog 13 to a point in front of the dog 14 andat the next step is brought into line with final pressure-jaws 71 and72, corresponding in form to the jaws 61 and 62 and carried by a slide73, which is operated by a slide 74, having a lug on its under side tostrike the slide 73 to move it forward, while the end of the slide 74,striking a shoulder 76, moves the slide 73 backward, the slide 74 beingoperated by a lever 77, actuated by a cam-groove 78 on a cam 79 on theshaft 11, which is geared to the shaft 33. As the jaws 71. and 72advance they close together and press the paper or fabric which has beenpasted to the end of the steel, the pressure of the jaws being somewhatgreater than the pressure 'of the jaws 61 and 62, so as to give it moreof a squeezing or pressing effect and secure better adhesion. When thesejaws retire to release the steel, it is delivered onto a belt 80, bywhich it is carried to a suitable receptacle. (Not shown.)

The two sides of the machine are operated by the shaft 11, which isdriven by a main pulley 81. In order to accommodate steels of differentlengths or when only one end of the steel is to be tipped, the frame atthe left of the machine is arran ed to slide upon a bed 82 and be movedt hereon by a screwshaft 83, which is held against longitudinal movementby a lug 84, through which it passes, and which has threaded engagementwith the frame, so that by turning the screw in one direction or theother the left-hand frame is moved toward or from the righthand frame.
